Solution for ln(x+2)=ln(5-x) equation:


Simplifying
ln(x + 2) = ln(5 + -1x)

Reorder the terms:
ln(2 + x) = ln(5 + -1x)
(2 * ln + x * ln) = ln(5 + -1x)
(2ln + lnx) = ln(5 + -1x)
2ln + lnx = (5 * ln + -1x * ln)
2ln + lnx = (5ln + -1lnx)

Solving
2ln + lnx = 5ln + -1lnx

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-5ln' to each side of the equation.
2ln + -5ln + lnx = 5ln + -5ln + -1lnx

Combine like terms: 2ln + -5ln = -3ln
-3ln + lnx = 5ln + -5ln + -1lnx

Combine like terms: 5ln + -5ln = 0
-3ln + lnx = 0 + -1lnx
-3ln + lnx = -1lnx

Add 'lnx' to each side of the equation.
-3ln + lnx + lnx = -1lnx + lnx

Combine like terms: lnx + lnx = 2lnx
-3ln + 2lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-3ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-3 + 2x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-3 + 2x)' equal to zero and attempt to solve: Simplifying -3 + 2x = 0 Solving -3 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 2x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2x = 0 + 3 2x = 0 + 3 Combine like terms: 0 + 3 = 3 2x = 3 Add '-2x' to each side of the equation. 2x + -2x = 3 + -2x Combine like terms: 2x + -2x = 0 0 = 3 + -2x Simplifying 0 = 3 + -2x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
